摘要
提出基于交替活跃的部分连接网络的休眠调度策略,无须进行拓扑控制,支持较高的休眠/活跃比率,显著提高了网络平均寿命。给出了满足延迟要求的休眠时间表的确定方法。提出簇内休眠相位同步和簇间相位次序调整的主动调节方法。仿真表明,该方法显著降低了端到端的延迟。
A scheme of sleep scheduling based on partially connected network in alternately active mode was proposed. Without need of topology control, the method had high sleep/wake ratio thereby significantly extending the lifetime of network. A method was given to set the sleep-wake cycles according to maintain the responsiveness, The proposed sleep scheduling synchronizes the phase and cycle of sleep within clusters while differentiates phase among clusters, Simulation shows that these methods can significantly reduce the end-to-end delay.
